Batman vs. Superman filming is almost set to begin! The rumored start date is May 19th and this past weekend at the Garden Bowl in downtown Detroit, a Batman vs. Superman cast party was held for the crew.

Comicbook.com contributor Thomas Williams was at the Garden Bowl and was able to snap a few photos. He spotted Henry Cavill and girlfriend Gina Carano, director Zack Snyder, and production designer Patrick Tatopoulos. He thought he saw Gal Gadot as well, but wasn’t able to get a photo.
